The fuse cannot be made externally accessible. Reverse polarity at the input will cause the fuse to blow but no other damage. Note: Fuse is not customer-accessible. Table 3: Fuse specification Model Fuse type Fuse rating CDP200/250 slow blow T 250 V, 12.5 A Inrush Current Limitation The CPD Series incorporates an active inrush current limiter in the input circuitry, which reduces the peak inrush current value by a factor of 10 – 15 to protect connectors and switching devices from damage. high current synchronous rectifiers supply the 5 V and 3.3 V outputs with up to 40 A. The secondary controlled +12 V post regulator is supplied by an additional winding of the

3.3 V main transformer, and the linear regulator for the

–12 V output is supplied by the output choke of the +12 V output. After rectification, the output filter reduces ripple and noise to a minimum without compromising the dynamic response. All outputs are protected from the bus by decoupling FETs or diodes. A current monitor calculates the output power. As soon as the output power exceeds the maximum threshold level, the converter starts to reduce the output power by decreasing the output voltages. In contrast to the outputs 5 V, 3.3 V and +12 V with active current sharing, the –12 V output has a droop characteristic for passive current sharing. Each converter has a switching frequency of around 135 kHz. Power-One's Efficient Dual Geometric Edge (EDGE TM) Technology facilitates high current density, increases reliability by reducing component stresses, and decreases the amount of heat dissipated. The backbone of this patented technology is an interleaved, multi- channel forward converter utilising transitional resonant switching techniques and proprietary leading and trailing- edge pulse width modulation. It has a proven track record in high-availability power solutions. Note: The inrush current limitation is achieved using an electronic circuitry. For effective limitation the converter should not be switched on and off more frequently than every 8 seconds. Input Transient Protection A metal oxide VDR (Voltage Dependent Resistor) together with the input fuse and suppressor diode form an effective protection against high input voltage transients, which typically occur in most installations. The CPD Series input range and input filters have been designed and tested to meet the requirements of EN 61000-4-5, criterion B. Reverse Polarity The converters are not protected against reverse polarity at the input to avoid unwanted power loss. In case of reversed input voltage, the suppressor diode conducts blowing the fuse, but preventing further damage.

Using the hot-swap capability, the output voltages may deviate dynamically by max. 5% during the plug-in / plug-out operations. Output Protection and Current Limitation The outputs are fully protected against continuous open circuit (no load) and also against continuous short circuit. All outputs have a constant current limitation with a rectangular characteristic (see figure below). The total current from the main power trains Vo1, Vo2 and Vo3 is limited by P o max. So there is a free choice of load distribution between these outputs. Fig. 2 Current limitation behavior of a CPD. 1.0 0.95 0.5 Vo/Vo nom Io Io nom Io max Io L 05186a

NOV 28, 2006 revised to JAN 29, 2007 Page 6 of 13 www.power-one.com CPD Series Data Sheet 200 – 250 Watt CompactPCI® DC-DC Converters Thermal Considerations If a converter CPD is mounted in an upright position with air flow of 250 LFM (CPD200) or 400 LFM (CPD250) allowing unrestricted forced air cooling, and is operated at its nominal input voltage and power at maximum ambient temperature T A max (see: Temperatures), the temperature measured at the measurement point of the case temperature T C (see: Mechanical Data) will approach the indicated maximum value TC max (105 °C) after an initial warm-up phase. However, the relationship between TA and TC depends heavily on the operating conditions and system integration. The thermal conditions are influenced significantly by the input voltage, the output current, the airflow, and the temperature of the adjacent elements and surfaces. T A max is therefore contrary to TC max only an indicative value. Fig. 3b Output power versus temperature TA (CPD250) Caution: The installer must ensure that under all operating conditions TC remains within the limits shown in the diagrams fig. 3 valid for a converter mounted in free and quasi-stationary air, allowing unrestricted convection cooling. Note: Forced-air cooling or an additional heat sink can improve the reliability or allow T A to be increased above TA max provided that TC max is not exceeded. Thermal Protection A temperature sensor fitted on the main PCB provides an over temperature warning (degrade) signal 15 °C before the temperature T c max at which the thermal derating begins to reduce the output power. The output power returns to the nominal value, if the temperature drops back below this limit. See Temperature Warning and Shut-Down. Auxiliary Functions Inhibit The inhibit input enables (logic high, pull up) or disables (logic low, pull down) all outputs, if a logic signal (TTL, CMOS) is applied. In systems consisting of several converters this feature may be used to control the activation sequence of the converters by means of logic signals, or to enable the source to start up, before full load is applied. Note: If this function is not used, the inhibit pin 39 can be left open (not connected). If pin 39 is connected to a return (e.g. Fig. 4 Definition of Vinh. pin 24), the internal logic will disable all outputs. The inhibit input is protected by a decoupling diode.

Its output signal Vfail changes from high to low impedance, when one of the monitored voltages falls below the threshold level; V fail changes back to high impedance, when the monitored voltage exceeds the threshold level again. The threshold levels correspond to approx. 90% of V i min and approx. 85% of Vo nom. Connector pin 42 (fail signal Vfail) is internally connected via the drain-source path of a JFET (self-conducting type) to the signal return pin 22. The current I fail should not exceed 2.5 mA. The JFET is not protected against overvoltage; V fail should not exceed 40 V. Fig. 8 Power Fail: JFET output, Ifail ≤2.5 mA. Temperature Warning and Shut-Down The temperature warning circuitry monitors the case temperature. Its output signal changes from high to low impedance, when the case temperature exceeds the upper threshold level, and changes back to high impedance, when the case temperature falls below the lower threshold level. Pin 38 (degrade signal V DEG#) is internally connected via the collector-emitter path of an NPN transistor to the signal return pin 22. The current I DEG# through should not exceed 40 mA. To prevent the NPN transistor from damage, V DEG# should not exceed 40 V. If the case temperature TC exceeds 105 °C, the converter will be disabled. It resumes operation, once TC falls below 105 °C.

This feature allows the compensation of voltage drops across the connector contacts and if necessary, across the load lines. To ensure correct operation, each sense line (S+ and S–) should be connected to its respective power output (Vo+ and Vo–). Note: All outputs have a common sense return. The voltage difference between any sense line at its re- spective power output pin (as measured on the connector) should not exceed the following values. Note: The output terminals Vo+ and Vo– must always be connected to the load before connecting the sense lines S+ and S–, otherwise the converter will be damaged. Note: If the sense lines S+ and S– compensate for a considerable voltage drop, the output loads shall be reduced in order to respect the maximum output power. Enable Connect enable pin 27 (EN#) with signal return pin 22 (RTN) externally to start the converter. Pin 27 is shorter than the others ensuring startup only when all other pins are already connected to the system providing a true hot- swap capability.

Not more than six converters should be connected in parallel. Using this feature reduces the stress on the individual converters and improves the reliablity of the system. Interconnection of the current sharing terminals causes the converters to share the output current evenly. In n+1 redundant systems a failure of a single converter will not lead to a system failure, since the outputs are already decoupled by FETs and diodes internally. Passive Current Sharing for Vo4 The output voltage changes slightly with the output current (droop characteristic) ensuring automatic current sharing LEDs "Input OK" and "Fault" status versus input voltage.

NOV 28, 2006 revised to JAN 29, 2007 Page 12 of 13 www.power-one.com CPD Series Data Sheet 200 – 250 Watt CompactPCI® DC-DC Converters Installation Instructions These converters are components, intended exclusively for installation within other equipment by an industrial assembly process or by a professionally, competent person. Installation must strictly follow the national safety regulations in respect of the enclosure, mounting, creepage distances, clearance, casualty markings, and segregation requirements of the end-use application. Connection to the system shall be made via the mating female connector (see fig. 15). Other installation methods may not meet the safety requirements. Check for hazardous voltages before altering any connections. The converters are provided with a leading pin no. 45, which is reliably connected to the case. For safety reasons it is essential to connect this pin to the protective earth of the supply system, see also: Safety of Operator-Accessible Output Circuits. The Vi input (pin no. 46) is internally fused. This fuse is designed to protect the converter in case of over current, but may not be able to satisfy all customer requirements. External fuses in the wiring to one or both input pins (no. 46 and/or no. 47) may therefore be necessary to ensure compliance with local requirements. Important: If the inhibit function is not used, pin 39 (i) should be left unconnected to enable the outputs. Enable Pin 27 (EN#) should be connected to pin 22 (RTN) to enable the outputs. Do not open the converters, or the warranty will be invalidated. Make sure that there is sufficient airflow available for convection cooling. This should be verified by measuring the case temperature, when the converter is installed and operated in the end-use application. The maximum specified case temperature T C max should not be exceeded. Make sure that a converter failure (e.g., by an internal short-circuit) does not result in a hazardous condition. Cleaning Agents The power supplies are not hermetically sealed. In order to avoid possible damage, any penetration of cleaning fluids is to be avoided. NUCLEAR AND MEDICAL APPLICATIONS - Power-One products are not designed, intended for use in, or authorized for use as critical components in life support systems, equipment used in hazardous environments, or nuclear control systems without the express written consent of the respective divisional president of Power-One, Inc. TECHNICAL REVISIONS - The appearance of products, including safety agency certifications pictured on labels, may change depending on the date manufactured. Specifications are subject to change without notice. Standards and Approvals The converters correspond to class I equipment. All converters are UL-recognized according to UL 60950 and CAN/CSA C22.2 No. 60950, and approved by TÜV to IEC/EN 60950-1:2001. The following considerations have been made during design concerning safety :

• Build-in component
• Basic insulation between input and output, based on 75 VDC. The input is identified as TNV-2.
• Operational insulation between output(s) and case
• Use in a pollution degree 2 environment. The converters are subject to manufacturing surveillance in accordance with the above mentioned UL standards and ISO 9001:2000. Isolation The electric strength test is performed as factory test in accordance with EN 50116 and EN/IEC 60950 and should not be repeated in the field (see table Isolation). Power-One will not honour any guarantee claims resulting from electric strength field tests.
